Float class floatValue() method

  • floatValue() method is available in java.lang package.
  • floatValue() method is used to return the value denoted by this Float object converted to type float (by casting).
  • floatValue() method is a non-static method, it is accessible with class object only and if we try to access the method with the class name then we will get an error.
  • floatValue() method does not throw an exception at the time of conversion from Float to float.

Syntax:

    public float floatValue();

Parameter(s):

  • It does not accept any parameter.

Return value:

The return type of this method is float, it returns a converted (from type Float to float) value represented by this Float object.

Example:

// Java program to demonstrate the example 
// of float floatValue() method of Float class

public class FloatValueOfFloatClass {
    public static void main(String[] args) {
        // Variables initialization
        float f1 = 30.20f;
        float f2 = 40.20f;

        // It returns the value denoted by this Float ob1 object
        // and converted to a float by calling ob1.floatValue()
        Float ob1 = new Float(f1);

        // Display ob1 result
        System.out.println("ob1.floatValue(): " + ob1.floatValue());

        // It returns the value denoted by this Float ob2 object
        // and converted to a float by calling ob2.floatValue()
        Float ob2 = new Float(f2);

        // Display ob2 result
        System.out.println("ob2.floatValue(): " + ob2.floatValue());
    }
}

Output

ob1.floatValue(): 30.2
ob2.floatValue(): 40.2
